To all whom, t may 0071/067171,.-

Beit known that I, CHARLES M. ALLEN, a citizen of the UnitedStates,residing atl/*Worcester, in the county of Worcester andCommonwealth of Massachusetts, have invented a new and usefulImprovement in Flow-Registers, of which the following is aspecification, accompanied by drawings, forming a part of the same, inwhich- Figure 1 is a view in perspective of my improved dow-register,showing it applied to and operatively connected with the turbinewheel.Fig. 2 is an enlarged view, in front elevation, of the How-register.Fig. 3 is a side elevation of thesame, and Fig. 4is an enlarged view ofthe diaphragm. Fig. 5 is a detached sectional View, on an enlargedscale, of the oil-receptacle in the turbine-casing.

Similar reference letters and figures refer to similar parts in thedifferent views.

In most places where water-power is sold the water-head is kept nearlyconstant, and observations of it would be required only at longintervals and at times of high or low water. The varying factor then isthe amount of gate-opening, and the accuracy of the results will dependlargely on the frequency of the reading of this factor. It was toobviate the trouble and expense incident to making these readings thatthe present invention was devised; and the object of my presentinvention is therefore to provide a simple and accurate water-meter toautomatically measure and record with accuracy the two variablesnamely,the gate-opening and the water-head acting on the wheel; and with theseobjects in View my invention consists in certain novel features ofconstruction and combination of parts, which will be hereinafterdescribed, and pointed out in the claims.

Referring to the accompanying drawings, 1 denotes the turbine-cylinder,into which water is supplied through the pipe 2 and out through theopposite ends of which the water discharges through the pipes 3 3 intothe tailrace, as shown in Fig. 1, these parts being mounted in asuitable framework 4 and supported on a bridge-plate 5 in any approvedmanner. The turbine-wheel (not shown) rotates within the cylinder 1 inthe usual manner and is keyed or otherwise secured upon the driven shaft6, which turns in suitable bearings 7 7 provided therefor. An ordinarygate (not shown) is employed, and the shaft 9 which operates it has ahand-wheel 8 on its forward end, by which it is turned to regulate theextent to which the gate is opened, and to this shaft 9 is secured thesprocketwheel 10, and the purpose of this sprocketwheel will be fullyexplained hereinafter.

Mounted upon a shelf A in a convenient location are two cylinders 11 and12, having mutilated gear-teeth 11a and 12 thereon, respectively, andsupported one above the other, as shown, upon a vertical shaft 13, whichlatter is supported at its ends in the frame 14 of the register. Theupper cylinder is termed the head-cylinder and the lower thegatecylinder. These two cylinders are independent of each other,although supported on a common axis, and the gate-cylinder 12 is securedto the shaft 13, whereas the head-cylinder is Lloosely mounted thereon.The gatecylinder is provided with a worm-wheel 15 at its lower end, andthe worm 16 on the shaft 17 engages the worm-wheel and rotates thegate-cylinder 12 continuously and uniformly, the shaft 17, which turnsthe cylinder 12, being driven by the turbine-shaft 6 through thecross-belt 18, passing over the pulleys 19 and 20, secured to the twoshafts 17 and 6, respectively, as shown in Fig. 1. One odge of thetoothed section on the cylinder 12 is straight, as shown at 21, andparallel with the axis of rotation, whereas the opposite or mutilatededge of the teeth (indicated at 22) is variable upon a line extendingspirally around the cylinder 12. The mutilated or variable edge 22starts at the lower edge of the cylinder, as shown in Fig. 2, from thestraight edge of the toothed section, which latter is the length of thecylinder, and from this point the remaining teeth diminish in length asdeiined by the variable line 22 until it arrives at nothing at the upperend of the cylinder at a distance from the edge 21, as shown in Figs. 2and 3. A pinion 23, Fig. 3, is in position to operate in connection withthis cylinder and is mounted in a carriage 24, guided in its movementsby the shaft 28, and has a spline connection with a shaft 25, upon whichit is capable of sliding, but not turning. A sprocket-chain 26 issecured to this carriage 24 and passed over the sprocket-wheel 27 on ashaft 29 and sprocket-wheel 27LL on a shaft 27h, and the shaft 29 isdriven' by a sprocketchain 26, passing around the sprocket-wheel 10 onthe gate-screw 9 and sprocket-wheel 27c on one end of the shaft 29, asshownin Fig. 1. In this way the position of the carriage 24 with respectto the height of the cylinder 12 is determined by the extent to whichthe IOO gate Ais opened or closed through the turning of the gate-shaft9. When the gate begins to open, the carriage 24 is opposite the extremelower end of the cylinder 12 and a complete revolution of the cylinder12 is necessary to turn the pinion 23 the distance of one tooth, whereasthe further opening of the gate causes the carriage 24 to be raisedhigher upon the shaft 25, and as it is raised higher more teeth of themutilated gear engage the teeth of the pinion 23, turning the lattercorrespondingly, and when the gate is opened to its fullest capacity thecarriage, with the pinion 23, is raised to a point opposite the extremeupper end of the cylinder 12 and the pinion 23 is given the maximumnumber of rotations. The rotations of the gate-cylinder 12 are recordedby a register 30 of any known and suitable form of construction, abevelpinion 31 being secured on the upper end of the shaft 13 inposition to drive a bevel-pinion 32 on the shaft, (not shown,) whichactuates the mechanism of the register in the customary manner.

The head-cylinder 11 has its gear-teeth arranged similar to those of thegate-cylinder 12. One edge 33 of the toothed section 11 is straight andparallel with the axis of the cylinder and the opposite edge 34 of thetoothed section is curved, as shown in Figs. 2 and 3. A pinion 35 isdesigned to intermesh with the teeth 11a of the head-cylinder and bedriven thereby, and this pinion 35 is mounted in a carriage 36, whichlatter also carries a pinion 37, engaging the pinion 35 and having aspline connection with a shaft 28, on which the pinion 37 slides. Thehead-cylinder 11 is driven by a pinion 38, secured to the upper end ofthe shaft 25, and as the shaft 25 is rotated by the gate-cylinder 12through the pinion 23 the movement of the head-cylinder 11 coincideswith the movement ofthe gate-cylinder 12. The position of the carriage36 is determined by the water-head in the turbine 1 in the followingmanner: Within the turbine-casing an oil-reservoir is located. Thiscomprises two cups 39 and 40, Fig. 1, the cup 40 opening downwardly andlocated within the cup 39, which is open at its upper end to the waterin the turbine-case 1. rl`he upper portion of the cup 40 is filled withoil, as shown at 40, Fig. 5, and from it a pipe 41 leads to the chamber42. (Shown in Fig. 1 and on a larger scale in Fig. 4.) The chamber 42 iscovered with a diaphragm 43, which is submerged in the tail-race, withits upper surface exposed to the water therein. The pressure of thewater in the turbine-case acting upon the oil in the cup 40 istransmitted to the under side of the diaphragm 43 and is balanced by aspring 44 acting against the upper side of the diaphragm. The diaphragm43 is connected by a rod 45 with one end of a multiplying-lever 46. Theopposite end of the lever 46 is connected by a rod 47 with thel carriage36,carrying the intermeshing pinions 35 and 37. rl`he rotation of theshaft 28 is recorded by a register 46 of any known and suitableconstruction, through a bevel-pinion 47 on the upper end of the shaft 28and a pinion 48 on a shaft 49, which actuates the mechanism of theregister 46.

The operation of my How-register is as follows: The rotation of theturbine imparts a slow rotary motion to the lower gate-cylinder 12. Themutilated gear 12 imparts an intermittent rotary motion to the pinion23, the extent of the rotation of the pinion 23 being determined by thevertical position of the pinion as the carriage 24 is raised by theopening of the gate. The rotation of pinion 23 is imparted to the upperor head cylinder 11, which, through its mutilated gear 11 and pinions 35and 37, imparts an intermittent motion to the shaft 28, and the rotationof the latter is registered by the register 46. rIhe rotation of theshaft 28 as driven by the headcylinder 11 is determined by the verticalposition of the carriage 36, and this is controlled by the pressure ofthe head of water in the turbine-case 1. The rotation of the shaft 28 isltherefore a resultant of two forces--to wit,

the pressure of the head of water acting on the wheel and the iiow ofwater past the wheel as measured by the rotation of the wheel itselfacting as a meter. Any variation in the opening of the gate will varythe position of the pinion 23 on the gate-drum, and any variation in.the pressure against the under side of the diaphragm 43, which of coursewill occur with any variation in the head of water, will change theposition of the pinion 35 on the head-drum. A change in the position ofthe pinion 23 varies the rotation of the head-drum, Which also affectsthe movement of the pinion 35, and a change in the position of thepinion 35 on the head-drum still further varies its movement, and theresultant of these two changes is registered at the register 46, whichis arranged to record the quantity of water flowing through the wheel ata given number of revolutions of the wheel or during a given period oftime when the rate of speed of the wheel is known.
